'More confidence about the results': FDA authorizes two rapid coronavirus tests for home screening
Consumers will soon be able to buy rapid coronavirus tests at chain pharmacies and grocers without a prescription after the Food and Drug Administration on Wednesday authorized two home tests.
The BinaxNOW coronavirus self-test will include two tests per kit for serial screening. The no-prescription test will deliver results in 15 minutes and does not require a lab. The FDA also authorized the Quidel QuickVue coronavirus test, which delivers results in 10 minutes and also can be used without a prescription.
The FDA has authorized more than 300 coronavirus tests and technologies in what's becoming an increasingly crowded field of medical labs and tech firms touting different technologies.
The federal agency authorized only two other no-prescription home tests, but the companies that make those tests are ramping up production, and the tests not yet available to purchase. Several more tests allow people to collect nasal or saliva samples at home, but people must send samples to a lab, which delays results for one to two days.
But by greenlighting the Abbott and Quidel tests that can be purchased by consumers without a prescription, the federal agency is significantly expanding access to testing for Americans. The authorization comes two weeks after the agency announced a streamlined path for serial testing to screen people without symptoms.
Abbott's test should be administered twice over three days with 36 hours between tests. Quidel's test should be used twice over three days with 24 to 36 hours between tests.
"The benefit is it gives you more confidence about the results," said Mary Rodgers, an Abbott principal scientist. "If you catch someone at the right time in their infection, testing more than once will give you more opportunities to find any positive results when someone is most infectious."

Abbott’s home test is the same version widely used in nursing homes, schools and workplaces, and the company says the tests will soon be available for purchase at food, drug and mass merchandise retailers yet to be named. The company has the manufacturing muscle to make and ship 50 million rapid tests each month.
Abbott will sell the two-test kits to retailers for less than $20. Retailers will set prices, but Abbott officials said prices should be comparable or cheaper to other health tests sold directly to consumers.
Quidel said that it will announce retail partnerships in the coming weeks and that its test will soon be available for purchase. The company is building a factory that will open later this year with a capacity to make more than 50 million QuickVue rapid antigen tests each month, according to a news release.
Advocates of screening with inexpensive rapid antigen tests say home tests are an important step to give consumers the option of testing themselves without visiting a doctor or telehealth provider – extra steps that take time and cost money.
Michael Mina, an infectious disease epidemiologist at the Harvard T.H. Chan School of Public Health, said frequent testing can prevent Americans from unknowingly spreading the virus. He believes the frequent testing used in tandem with vaccination will limit the spread of COVID-19.
“Frequent rapid testing will be important in the months and years to come as we understand more about how long immunity lasts from the vaccine and how variants evolve,” he said.
The Abbott and Quidel tests can be used on children 2 years old or older when adults handle the samples. Adults and most teens will be able to administer their own tests.
The Abbott kit comes with a nasal swab, reagent solution and a test card. Users administer the swab to their nose to obtain a sample and insert the swab in a test card. Similar to a pregnancy test, the card displays results within 15 minutes.
